5.11 Connecting devices for Wi-Fi or a mesh 
network
If the T-Mobile High-Speed Internet Gateway is to be used for Wi-Fi, connect devices 
that are going to use Wi-Fi for service and communications through the T-Mobile 
High-Speed Internet Gateway by using the SSID and Wi-Fi key shown on the 
underside of the T-Mobile High-Speed Internet Gateway.
To connect a WiFI device using SSID and password, using your phone, select the 
the correct Wi-Fi network name, then enter the SSID and password. 
If the T-Mobile High-Speed Internet Gateway is to be used as the access point of a 
Mesh Wi-Fi 6 System, see section 4.9.
5.12 Connecting Ethernet LANs
In addition to supporting the Mesh Wi-Fi 6 system on the LAN side, the T-Mobile 
High-Speed Internet Gateway also supports connection of up to two Gigabit Ethernet 
LAN ports.
Before connecting a Gigabit Ethernet LAN to the T-Mobile High-Speed Internet 
Gateway, observe the LCD screen, which displays the CONNECTION screen. Tap 
the LCD screen four times to display the DEVICES screen. 
You connect a Gigabit Ethernet LAN to the T-Mobile High-Speed Internet Gateway 
by connecting the cable from the Ethernet LAN to any of two Gigabit Ethernet LAN 
ports on the backside of the T-Mobile High-Speed Internet Gateway. 
Figure 17 shows the location of the Gigabit Ethernet LAN ports.
